user outputs 
io_out
to the gpio pads need the corresponding 
io_oeb
to be low. Otherwise the output is disabled. The oeb check is for this.
Can you share your 
precheck_results/<tag>/tmp/cvc.oeb.report
and 
precheck_results/<tag>/tmp/cvc.oeb.log
files?

can I connecte io_oeb to LA pins to make it configurable?instead of making it permanently as output?
m
That sounds like a valid solution. However, with a direct connection, the OEB check probably still fails. Can you run your LA pin through a buffer before 
io_oeb
?

@Mitch Bailey I am also getting an FEOL error but when I try to open the mask in layout the file gives error,so I am not sure how to debug it

@samarth jain I think that’s due to an older version of 
klayout
. Do you have 
0.27
or 
0.28
?
